COMBINATION GAUGE.

Specification of Letters Patent.

Application filed- September 16, 1920. Serial No. 410,600.

i T 0 all whom it may concern Be it known that I, EDGAR G. Morin, Jr., a citizen of the United States, and resident of San Francisco, county of San Francisco, State of California, have invented new and useful Combination Gauge, of which the following is a specification.

The present invention relates to an improved gauge which is especially adapted for use by carpenters joiners and like workmen in the marking of striking plate, lock, hinge mortise and other similar cuts on door jamb rabbets and similar structures.

The primary object of the invent-ion is to provide a simply constructed, compact, inexpensive, substantially constructed accurate and easily adjustable gauge which, after simply and easily effected adjustment, may be used for making various markings without necessitating readjustment for each different marking. l

Another object of the invention is to provide a gauge of' he character described which may be made of stamped bent or folded sheet metal and will be small and light and may be conveniently carried in the pocket.

The invention possesses other advantages and features, some of which, with the foregoing, will be set forth at length in the following description wherein shall outline in full that form of the invention which l have selected for illustration in the drawings accompanying and forming a part of the piesent specification. ln said drawings l have shown one form of the construction of my invention but it is to be understood that l. do not limit myself to such form, since the invention as expressed in the claims may be embodied in a p-lurality of forms.

Referring to the drawings Figure 1 is a top plan view of the gauge showing it as it would appear when applied to a door and jarnb, parts of which latter are shown in section; there being also shown a fragmentary plan of the gauge at one end as applied for marking a hinge mortise. Figure 2 is a perspective view of the gauge showing it completely assembled, Figure 3 is a longitudinal sectional view taken through the gauge, Figure 4 is a transverse. sectional view of the gauge, Figure 5 is a perspective view of certain parts of the gaugel shown in pre-assembled relation, Figure 6 is a perspective view of a detail of the invention, Figure 7 is a perspective'viewof another detail of the invention and Figure 8 is a perspective view of one of the adjustable plates.

The'preferred embodiment of the gauge comprises rigidly joined rectilinear body plates (2) and (3) overlapped where joined and spaced in parallel relation to one another for the most part. On the upper and lower sides of these plates are secured plates (4) and (5) having tongues (5a) and shoulders (5b) at their ends, the shoulders (5b) being flush with the outer ends of the body plates. The tongues extend into openings (5C) formed in end plates (6) and (7) with the shoulders abutting said end plates. .The end plates project outwardly equally at their ends from the outer sidel of the plates (4) and (5) and also project outwardly an equal distance from the plates (2) and (3). These elements form a rectangular box-like body.

Similar longitudinally adjustable gauge members (8) and (9) are mounted upon the plates (3) and (2) respectively with their outer ends projecting beyond the plates (6) and (7). At one end the member, (9) is provided with an inverted U-shaped gauge member (11) having parallel gauge portions (10) and (12) adapted to rest upon opposite faces of the door as shown at a and c of Figure l, during the gauging and marking of the hinge mortise and other cuts. The member (8)v has an inturned right angular butt ange (13) on its outer end for engagement with the jamb rabbet shoulder as shown at b and the member (9) has a similar flange (14) for engagement with the jamb rabbet shoulder at d. Screws (15) and (16) are inserted through longitudinal slots (25) and (26) in the members (8) and (9) and operate in threaded openings (16) in the plates (2) and (3) so as to adjustably hold the members (8) and (9) in place. Screws (17) and (18) are inserted fromv the outside through the plate (4) for the purpose of actuating a clamping member which will be later described. A scribing point (19) is formed on the edge of the plate (6) which edge projects beyond the plate (3) and this point is in line with the slot (26) in the member (8) and projects outwardly beyond said member r(8). A similar scribing point (20) is provided on the opposite edge of the plate (7) and this point is in line with the slot (25) and projects beyond the member (9). A scribing point (21) is provided on the oppositeA edge of the plate (7) in the Patented J an. 3, 1922.

same plane `with thepoint (119') and projects through the slot (26).

The Plat@ (3l besa. right angulares@ (27) which has a scribing point (22) there on which point projects through' the plate (2) an)d through the slot (26) in the membcrjy `9 iii' tlie plane of the point (20), the member (11) being betweenthese points.-

The plate (2) is provided with arigh't angular flange (23)` corresponding to the one (27) and spaced therefrom. The flange (28) abutstheplate (3) onlits' freeend and has a projection (32) which `is riveted in the plate (3') to lock the plates andl firmly together. f j l j Other scribing points (23) and (24) are provided on U-lshaped gauge members (30) and (31) which are slidably mounted in the hollow space of the body between the plates (2), (3), (4) and (5) and the members (3) and (9).` The U-shaped gauge members (30) and (31) are adjustably heldin place by'a clamping plate (29) against which the ends of the screws (17) and (18) abut; By screwing in these screws the platev (29) 'is forced to frictionally engage and clamp the members (30) and (31). The flanges (27) and `(28) are notched on one edge as at (29') so as to accommodatesaid plate (29) and permit of a symmetrical body, formation as shown particularly in Figure 5. The point (23) is formedv on the endofthe member (30) and projects through the slot (25) a distance equal to the projection of the point (22). The point (24) is formed on the opposite end of the member (31) and projects through the slot (26) as does the point (21). Opposite sides of the members (30) and (31) are engaged bythe plates (29)V and ('5) and the ends of said members engage the members (8) and (9) whereby the said members (30)'and (31) are snugly and accurately seated inthe body and accuracy of gauging and marking is provided. A scribing point (25) is provided on the free edge of the flange (13). This point is in line with thel other points but in a plane between the plane oi the other ponts and is for the purpose of marking the depth of the hinge leaf mortise along the face of the door as at E in Figure 1.

Operation--To mark the cut for the lock at the front edge of the door parallel marks spaced apart equal to the width of the face of the locks are cut in said edge. This is gauged by loosening the screw (18) and moving the member (30) so as to bring the point (23) a distance from the fixed point (22) equal to the width of thelock. The screw (18) is then tightened and the clamp plate (29) is caused to Jfrictionally engage and hold the member (30) and point (23) in adjusted position. These points (22) and (23) are next positioned or centered upon The point (22) is in line `with and" the" dbor s as to assume' the position* shown at a-in Figure l, by movin the member (9) so that thegauge surface(v 10) is the proper distance `from the fixed point (22) whereby thepoints will be centered. The screw (15) is` then tightened to hold the plate (9) in adjusted., position. The operator now places the surface (10) against the edge of the door and moves the `gauge up and down with the points (22) and (23) pressing lupon the edge ofthe door so as to markl the width of the lock cut. j

To gauge the .pointsy (21) and (24) forth'e striking plate marking on the" jamb lrabbeft as'shown at 6 in Figure l, thev member (31) is moved to bring the point (24) a distance from the fixed point (21) equal to the width of the striking plate and the set screw ('17) is tightened so as to press the clampv plate (29) upon and hold the member(31')` and' point (24) in adjusted position. The mem*- ber (8)*is neXt moved so as t'o bring the butt-flange (13) into engagement with the shoulder of the jamb rabbet as at b inV Figure 1, whereby the' points (21)" and (24') may be positioned to mark at the desired points on the jamb rabbet. The screw (1:7) is then tightened and the flange (13) isset in position. )Vith the butt-Hangs (13?)1'an`d points in the position by now` moving the gauge vertically and applyingiinward pres"- sure thereto the striking plater mortiseA will be marked on the jamb rabbet. With the gauge adjusted as'described for marking the lock and the striking plate cuts it is possible to readily and easily mark -a plurality of such cuts without necessitating any readjustment of the gauge.

To use the gauge Afor marking hingemortises on the door at the point C in Fi 'ure 1 and the hinge mortise on the j amb rabbet at Z in Figure 1, the member (19) may be adjusted to bring the butt-liange (14') the desired distance from the fixedV point (19') although with the member (9) adjusted for marking the lock cut it is usually unnecessary to move or adjust the member (9') for this hinge mortise marking. With the `gauge in proper adjustment the butt-flange (14) is engaged with the j amb rabbet 'shoulder at l and the point (19) is pressed inwardly while the gauge is moved up and down. This marks, the inner line of the mortise for the hinge leaf on the rabbet lat (Z. By placing the gauge surface (12) against the face of the door as at C and moving the gauge up and down with the point (20) bearing on the door the mark for the other hinge leaf mortise will be made. The butt-Hangs (14) andthe gauge surface 12) are at the ends of the member (19) andwill beV approximately equidis# tantly spaced from the fixed points ('19) and (20) regardless of the adjustment of the member (9) except that the outer face iloo ilo

of the butt (14) is spaced farther from the point (19) than the surface (12) is from the oint (20), a distance equal to the thickness of the butt (14). Thus the mark is so cut on the jamb rabbet at d that when the hinge leaf is placed in the mortise there will be a clearance between the face of the door and the jamb rabbet shoulder equal to thickness of the butt-flange (14). This allows for warping, etc.

To mark the depth of the hinge leaf mortise the plate (8) is adjusted to bring the point (25) at a point spaced from the outer face of the end plate (7) a distance equal to the thickness of the hinge leaf. The screw (16) is then tightened so that the parts will be held in this adjusted position. The outerl side of the end plate (7) is then placed upon the edge of the door as shown at E in Figure 1 and the point (25) is engaged with the face of the door near the edge. The gauge is moved up and down the length of the hinge and the depth mark of the hinge leaf mortise will be scribed.

It will thus be seen that I have provided a marking gauge which may be put to different marking uses with little or no adjustment for each different use. Therefore with my gauge it is possible to mark the lock, hinge and other mortise cuts on a plurality of doors, jambs, etc., more expeditiously, accurately, and with less work than is the case with the ordinary gauge.
